Breadcrumb Rule Cards: Portable AI context rules

A searchable, portable context manager for AI coding assistants that follows you across devices.

Problem

Breadcrumb records everything on your Mac and makes it searchable for AI, but such tools are bound to one OS and their rules/context can't travel. Meanwhile, multi-agent setups suffer when shared state and tools cause conflicts. Users need a lightweight, portable way to turn AI decision context into reusable rule sets.

Solution

A local-first CLI/editor plugin that extracts fragmented AI context (e.g., from Breadcrumb logs) into structured rule cards (YAML/Markdown), with versioning, cross-device sync, and team sharing. Core is the rule-card format and import/export pipeline, compatible with Claude Code, Cursor, and Codex.

Users

Indie developers and small teams heavily using AI coding assistants, switching between Mac, Linux, and remote servers.

MVP

Parse common AI assistant logs/memory files into tagged rule cards; export cards to JSON/YAML and import into editor rule directories; provide CLI search and diff; minimal web preview of rule-card changes; semi-automatic extraction from pasted text.

Revenue

Open-source core + paid team sync/audit service ($8/user/month) or one-time desktop license.

Why now

AI coding assistants are exploding, but context management is still fragmented; big players won't build cross-assistant rule portability, so an indie can win with a narrow wedge and developer community distribution.
